Scarlets v Edinburgh (17:15)
Scarlets make two personnel changes and one positional switch from their 37-28 win over Bulls, as prop Shaun Evans and lock Morgan Jones come into the pack.
Sione Kalamafoni, who is leaving Scarlets for French second-tier side Vannes at the end of the season will captain the Welsh side in place of the injured Aaron Shingler.
Edinburgh have Hamish Watson back but Dave Cherry was a late withdrawal.
They also have centre Damien Hoyland returning from injury as they make four changes from their 19-22 loss to Sharks, with lock Jamie Hodgson coming into the tight-five.
Charlie Shiel gets the nod at scrum-half and Hoyland's return sees Wes Goosen shift to full-back.
